Description

Technical Field

[0001] This utility model relates to the field of distribution boxes, specifically an indoor intelligent distribution box. Background Technology

[0002] Distribution boxes are electrical equipment characterized by their small size, easy installation, special technical performance, fixed location, unique configuration functions, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint, and environmental benefits.

[0003] In southern regions, due to geographical factors, the air humidity is high, and the "return to spring" weather often occurs. During the "return to spring" weather, the air humidity is too high. In damp conditions, moisture may reduce the insulation of the circuits in the indoor intelligent distribution box, causing short circuits. When the humidity is too high, there is a lot of water vapor in the air, which can easily cause the current to form an abnormal path through the water vapor, resulting in leakage. Moreover, the existing technology usually uses a closed dehumidification method, which slows down the heat dissipation of the distribution box and cannot solve both problems at the same time. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides an indoor intelligent power distribution box, comprising a housing, a dehumidification device disposed on the top of the housing, a through hole on the top of the housing connected to the dehumidification device, the dehumidification device comprising a dehumidification cylinder disposed on the top of the housing, the top of the dehumidification cylinder connected to the air inlet of an exhaust fan, a motor for driving rotation connected to the top of the exhaust fan, and a water outlet hose connected to the bottom of the dehumidification device. The dehumidifier cylinder includes an outer cylinder that is not closed at both the top and bottom and a rotating cylinder disposed inside the cylinder. The upper and lower ends of the outer cylinder are respectively connected to the air inlet of the exhaust fan and the through hole at the top of the housing. The rotating drum includes a first filter screen and a second filter screen with different diameters on the same axis. The first filter screen and the second filter screen are closed at both ends to form a space to accommodate dehumidifying particles, and a baffle is connected to the top. The baffle is connected to the bottom of the connecting shaft located above, and the top of the connecting shaft is connected to the impeller shaft of the exhaust fan.

[0005] Furthermore, a first guide plate and a second guide plate are respectively provided at the upper and lower ends of the rotating drum.

[0006] Furthermore, the bottom of the baffle is provided with a conical tube to guide the airflow.

[0007] Furthermore, the bottom of the water outlet hose is connected to the water storage tank.

[0008] Furthermore, the first guide plate is funnel-shaped with its smaller end facing into the rotating cylinder, and the second guide plate is symmetrically distributed with the first guide plate.

[0009] Furthermore, the side of the housing is provided with a vent, and the upper and lower sides of the vent are respectively provided with a first baffle and a second baffle with a semi-circular cross-section. The first baffle is located outside the second baffle to form a shaped air intake path.

[0010] Furthermore, the first and second stop levers are made of nano-desiccant.

[0011] Furthermore, the dehumidifying particles are calcium chloride.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model has a dehumidification device installed at the air inlet of the exhaust fan, and the rotating drum rotates continuously, so that the air can fully contact the dehumidification particles on the side of the rotating drum before entering the exhaust fan. This can maintain ventilation and cooling, and can also fully absorb and react with the water vapor in the air, so that the inside of the distribution box is kept dry and the operation is more stable. This invention utilizes two baffles located on the side vents of the casing to allow air to pass through an S-shaped air intake path and fully contact the baffles made of moisture-proof material for dehumidification. The combination of the air intake and exhaust ports further enhances the dehumidification effect. Attached Figure Description

Detailed Implementation

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0019] Examples, such as Figures 1-4 As shown: This utility model provides an indoor intelligent power distribution box, the structure of which includes a shell 1, a dehumidification device 2 disposed on the top of the shell 1, a through hole on the top of the shell 1 connected to the dehumidification device 2, the dehumidification device 2 including a dehumidification cylinder 22 disposed on the top of the shell 1, the top of the dehumidification cylinder 22 being connected to the air inlet of an exhaust fan 21, the top of the exhaust fan 21 being connected to a motor 20 for driving rotation, and a water outlet hose 23 being connected to the bottom of the dehumidification device 2; The dehumidification cylinder 22 includes an outer cylinder a that is not closed at both the top and bottom ends and a rotating cylinder b disposed inside the cylinder. The upper and lower ends of the outer cylinder a are respectively connected to the air inlet of the exhaust fan 21 and the through hole at the top of the housing 1. The rotating drum b includes two coaxial first filter screens b1 and second filter screens b2 of different diameters. The first filter screen b1 and the second filter screen b2 are closed at both ends to form a space to accommodate dehumidifying particles, and a baffle b3 is connected to the top. The baffle b3 is connected to the bottom of the connecting shaft c located above. The top of the connecting shaft c is connected to the impeller shaft of the exhaust fan 21, so that when the air passes through, it comes into contact with the dehumidifying particles for dehumidification. The connection can drive the rotating drum b to rotate, thereby increasing the contact area with the air and absorbing water vapor more thoroughly.

[0020] The upper and lower ends of the rotating drum b are respectively provided with a first guide plate a1 and a second guide plate a2, which can intercept and discharge the water droplets thrown out.

[0021] The bottom of the baffle b3 is provided with a conical tube b4 that guides the airflow, making the flow smoother and reducing resistance.

[0022] The bottom of the water outlet hose 23 is connected to the water storage tank 24, which can collect water droplets.

[0023] The first guide plate a1 is funnel-shaped with its smaller end facing the inside of the rotating cylinder b. The second guide plate a2 is symmetrically distributed with the first guide plate a1. The inclined arrangement of the first guide plate a1 can catch the water droplets thrown out, preventing them from falling into the distribution box and allowing the water droplets to flow smoothly into the water outlet hose 23. The arrangement of the second guide plate a2 can intercept the water droplets, preventing them from entering the exhaust fan 21.

[0024] The housing 1 has a vent 10 on its side. The upper and lower sides of the vent 10 are respectively provided with a first baffle 11 and a second baffle 12 with a semi-circular cross-section. The first baffle 11 is located outside the second baffle 12 to form an S-shaped air intake path, so that when the outside air enters, it can fully contact the first baffle 11 and the second baffle 12. The first baffle 11 and the second baffle 12 are made of nano desiccant, so as to perform preliminary dehumidification.

[0025] The dehumidifying granules are calcium chloride, which has a good dehumidification effect.

[0026] In practical implementation, the motor 20 drives the exhaust fan 21 to rotate and generate suction to draw air from the distribution box. The air in the distribution box enters the rotating drum b through the first guide plate a1. Under the guidance of the conical cylinder b4, it passes through the first filter screen b1 and the second filter screen b2. The dehumidifying particles between the first filter screen b1 and the second filter screen b2 absorb the water vapor that passes through. After the air enters between the outer cylinder a and the rotating drum b, it enters the air inlet of the exhaust fan 21 and is then discharged. Since the rotating drum b is connected to the impeller shaft of the exhaust fan 21 through the connecting shaft c, the rotating drum b can rotate continuously, thereby increasing the contact area with the air and improving the dehumidification effect. In addition, the centrifugal force generated by the rotation of the rotating drum b can throw the absorbed water to the outer cylinder a and flow out to the water storage tank 24 through the water outlet hose 23. Outside air enters the distribution box through the vent 10. As it passes through the vent 10, it flows upward under the action of the first baffle 11 and comes into contact with the second baffle 12. Under the obstruction of the second baffle 12, it flows downward into the distribution box. The arc shape allows the outside air to fully contact the first baffle 11 and the second baffle 12 before entering the distribution box, thus performing preliminary dehumidification. Combined with the dehumidification device 2, the dehumidification effect is further improved.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
